Just to clarify, this discussion is not about e85 versus alcohol injection. I said it in the first post, all it does is dilute the discussion and really is not the point I'm trying to get across. E85 is great, but not everyone can get it easily, not even me. I've said it 1000 times before, why it needs to get beaten to death just because we live in MN, I have no idea.
Back on topic, here's a great article that Richard @ Aquamist linked me to:
